As shown, the voice output means 211 and the voice input means 212 are connected to the voice input / output connector 220, and the voice input / output connector 220 is connected to the signal processor 230 and the controller 240, respectively. do. In addition, the terminal connection unit 280 is connected to the call detection unit 260, the call detection unit 260 is connected to the signal processor 230 and the control unit 240, respectively. In addition, the data storage unit 250 and the user control unit 270 is connected to the control unit 240, respectively.

The control unit 240 detects the combined detection signal of the voice input and output connection unit 220 and the terminal connection unit 280 to recognize that the voice output means 211 and the signal transmission unit 120 is connected to the incoming call detection The unit 260 is driven.

That is, when the voice output means 211 is coupled to the voice input / output connector 220, a predetermined combined signal is applied to the controller 240, and the terminal connection unit 280 is connected to the signal transmitter 120. When combined, a predetermined combined signal is applied to the controller 240. Therefore, the controller 240 senses that both the voice output means 211 and the signal transmission unit 120 are coupled to turn on the call detection unit 260.

Then, when a predetermined signal is received by the portable terminal 100, the received signal is transmitted to the call detection unit 260 through the signal transmission unit 120 and the terminal connection unit 280. Therefore, the incoming detection unit 260 detects the incoming signal through the terminal connection unit 280 and applies the incoming detection signal to the control unit 240. Therefore, when the incoming call detection signal is applied from the incoming call detection unit 260, the controller 240 reads out the incoming call sound stored in the data storage unit 250, and reads the incoming call sound through the signal processing unit 230. )

Thereafter, when the call-on signal of the user is applied through the user operator 270, the controller 240 controls the signal processor 230 to drive the voice signal of the user input through the voice input means 212.

3 is a circuit diagram illustrating a voice input / output connection unit.

As shown, the first power supply voltage VDD1 is connected to the output terminal OUT, and the voice input / output connecting means 221 is connected to a predetermined portion of the connection circuit, and the voice input / output connecting means 221 and the output terminal are connected. The second power supply voltage VDD2 is connected in parallel between OUTs.

Here, the voice input / output connection unit 221 is switched on before the voice input / output unit 210 is coupled, thereby applying the first power supply voltage VDD1 to an output terminal, for example, a first power supply voltage of 1.5V. Outputs (VDD1). Then, when the voice output means 211 is coupled to the voice input and output connector 220, the voice input and output connection means 221 is switched off. As the voice input / output connection means 221 is turned off, the circuit connected to the first power supply voltage VDD1 is opened to cut off the first power supply voltage VDD1, and the second power supply voltage VDD2 is connected to the output terminal OUT. Is approved. Here, the second power supply voltage VDD2 is preferably higher than the first power supply voltage VDD1, for example, 3V.

That is, the voice input / output connection unit 220 outputs a combined signal of 1.5V before the voice output unit 211 is coupled and 3V when the voice output unit 211 is coupled to the controller 240.

Here, the voice input and output connection means 221 is connected to the voice output means 211, for example, a circuit of the voice input and output connection part 220 when inserted into or withdrawn from the voice input and output connection part 220 as a connection jack. It is preferable to allow the short or open.

4 is a circuit diagram illustrating a terminal connection unit.

As shown in the drawing, the terminal connection unit 280 includes a signal transmission connection unit 282 and a third resistor R3 to form a closed circuit. An output terminal OUT is formed at one side of the closed circuit, and a third power source is formed at the other side. Voltage VDD3 is connected in parallel.

Therefore, before the signal transmission unit 120 is connected to the terminal connection unit 280, the signal transmission unit connection unit 282 is switched on and outputs the third power voltage VDD3 to the output terminal OUT. Therefore, the terminal connection unit 280 applies a high signal to the control unit 240 before the signal transfer connection unit 282 is coupled.

And, when the signal transmission connection means 282 is coupled to the terminal connection portion 280, the signal transmission connection portion 282 is switched off. Therefore, since the third power supply voltage VDD3 is blocked, the high signal is converted into a low signal and applied to the controller 240.

Here, the signal transmission connection means 282 is configured to be connected to the signal transmission unit 120, for example, it is preferably composed of a connection jack to short or open the circuit of the terminal connection unit 280. Or as described above is not formed as one component of the signal transmission unit 120, such as a connection jack is configured as a separate switch also corresponds to the subject matter of the present invention.

5 is a circuit diagram showing a call detection unit.

As shown, the incoming detection unit 260 has a power line connected to the gate of the switching element M1 and a power supply voltage VDD at the source side thereof, and the first to third transistors Q1 ˜to the input line In. Amplification means 261 composed of Q3) is connected, and a signal composed of first and second diodes D1 and D2 and fourth and fifth transistors Q4 and Q5 is connected to the amplifying means 261. The retaining means 262 is connected.

First, when a driving signal applied from the control unit 240 is applied to the gate of the switching element M1 through a power line POWER, the switching element M1 is turned on to convert the power supply voltage VDD into the amplifying means 261. To pass).

When an incoming signal is applied through an input line In connected to the terminal connection unit 280, the amplifying unit 261 amplifies it and transmits it to the signal holding unit 262. In detail, the first transistor Q1 and the second and third transistors Q2 and Q3 are sequentially turned on to amplify the incoming signal, and the signal holding means 262 is amplified by the amplifying means 261. The received incoming signal is rectified through the first and second diodes D1 and D2. The signal rectified through the diodes D1 and D2 sequentially turns on the fourth transistor Q4 and the fifth transistor Q5, thereby outputting the output terminal OUT connected to the emitter terminal of the fifth transistor Q5. A high or low level signal is output. That is, the amplifying means 261 amplifies the incoming signal which is AC, and the signal holding means 262 rectifies the amplified AC signal and outputs it to the controller 240 as a high or low signal.

6 to 8 are flowcharts illustrating a method of driving a portable player to which a hands-free function is added according to the present invention, and the operation of the present invention will be described in detail.

6 is a flowchart showing a preferred embodiment of the present invention.

In the driving method of the portable player 200 according to the present invention, a user connects the portable terminal 100 to the portable player using the signal transmission unit 120, and the audio output means 211 is connected to the portable player 200. And a driving step of the portable player 200 for driving the portable player 200 after connecting to the mobile terminal 200 (S100).

In addition, when an incoming call is detected from the portable terminal 100 after the driving step (S100) of the portable player 200, the portable player 200 outputs a ringing tone of the portable terminal 100 (S110).

Therefore, when the user recognizes an incoming call while the portable player 200 is being driven, the portable terminal 100 is operated through the voice output means 211 by operating the user operator 270 of the portable player 200 to turn on the call. Receives a voice signal received from. In addition, the user inputs his or her own voice through the voice input means 212 built in the portable player 200. Therefore, the voice signal input through the portable player 200 is transmitted to the portable terminal 100, and the portable terminal 100 transmits it.

At this time, the user operates the user manipulation unit 270 to select the background music or the call recording function so that the background music is output during the call, and also stores the contents of the call in the portable player 200 (S120).

7 is a flowchart illustrating a call detection step.

First, the controller 240 determines whether the portable terminal 100 is coupled. That is, the control unit 240 is applied from the terminal connection unit 280, for example, when the signal is converted from a high signal to a low signal when the signal transmission unit 120 connected to the portable terminal 100 is the terminal connection unit It is recognized that the coupled to (280) (S112).

In addition, as a next step, the control unit 240 determines that the voice output unit 210 is connected to the voice input / output connection unit 220. Therefore, in the voice input / output connector 220, for example, when a signal of 1.5 V is boosted to 3 V and output, the controller 240 recognizes that the voice output means 211 is connected to the voice input / output connector 220. (S113).

Therefore, when the controller 240 recognizes that both the voice input / output unit 210 and the signal transmission unit 120 are coupled, the control unit 240 switches the driving power to the call detection unit 260 through the power line POWER. The switching element M1 is turned on by being applied to the gate of the power supply voltage VDD so that the power supply voltage VDD is applied to the amplifying means 261. (S114)

Alternatively, the control unit 240 turns off the driving power of the incoming detection unit 260 when any one of the voice output unit 211 and the signal transmission unit 120 is not connected or the connection is boiled. Therefore, the incoming detection unit 260 is turned off by the switching element (M1) is cut off the power supply voltage (VDD) (S118) (S119).

Alternatively, when it is determined that both the voice output means 211 and the signal transmission unit 120 are combined as described above, the controller 240 receives the reception of the portable terminal 100 from the call detection unit 260. Determine (S115).

Therefore, when an incoming signal is transmitted from the portable terminal 100 to the terminal connection unit 280 through the signal transmission unit 120, the terminal connection unit 280 applies it to the reception detection unit 260. Therefore, the incoming call detection unit 260 converts the received incoming signal through the amplifying means 261 and the signal holding means 262 and converts the signal of a predetermined level to the control unit 240.

Therefore, the controller 240 recognizes the incoming signal and stops the output of the portable player 200, and reads out the ringing tone stored in the data storage 250. The controller 240 transmits the read ringing tone to the signal processor 230, and the signal processor 230 transmits the received ringing tone to the voice output means 211 through the voice input / output connection unit 220. Therefore, the user can hear the ringing tone through the voice output means 211 (S116) (S117).

8 is a flowchart illustrating a call step.

As described above, the controller 240 outputs the ringing tone through the voice output means 211 (S110), and then determines whether a call-on signal is applied through the user operator 270 (S121). Therefore, when a user hears a ringing tone output through the voice output means 211 and inputs a call on signal through the user control unit 270, the controller 240 recognizes this and determines the number of times of the call on switching signal. (S122).

Accordingly, the controller 240 controls the signal processor 230 to drive the signal on switching, for example, once, and outputs the communication signal received from the portable terminal 100 to the voice output means 211. do. Therefore, the user may listen to the received signal of the portable terminal 100 through the portable player 200.

When the user inputs his / her voice through the voice input unit 212, the input signal is transmitted to the signal processor 230 through the voice input / output connection unit 220 and the signal processor 230. Sets a path of the input signal and outputs it to the portable terminal 100 through the terminal connection unit 280. Therefore, the portable terminal 100 transmits an input signal transmitted through the terminal connection unit 280 (S123).

Thereafter, the controller 240 determines whether the user manipulation signal is applied from the user manipulation unit 270 and controls the component according to the input user manipulation signal (S124). That is, when the user selects the background sound reproduction through the user operator 270 during a call, the manipulation signal is transmitted to the controller 240. Therefore, the controller 240 reads the background music stored in the data storage 250 and delivers the background music to the signal processor 230. Therefore, the signal processor 230 sets the respective paths of the transmitted background music, the user's voice input, and the received signal of the portable terminal 100 to output the background music during the user's call (S125).

  Alternatively, when a call recording selection signal is applied from the user manipulation unit 270, the controller 240 stores the input voice, the background music, and the received signal of the portable terminal 100 in the data storage unit 250. (S126).

Preferably, the call recording selection signal or other selection signal is applied from the user control unit 270 during the background sound reproduction step, and the call recording operation is performed when the background sound reproduction selection signal is applied in the call recording step. It is also possible to start the background sound reproduction step.

Thereafter, the controller 240 determines whether a call off signal is applied from the user operator 270 (S127). Therefore, when a call-off signal is applied from the user operation unit 270, the background music playback or call recording is stopped and the path of each signal set in the signal processor 230 is turned off so that the voice output means 211 and the voice input means are turned off. The input / output of 212 is blocked (S128) (S129).

Here, the call-off detection of the controller 240 is released from the connection of the terminal connection unit 280 or the voice input / output connection unit 220 or the reception signal of the portable terminal 100 transmitted through the terminal connection unit 280 Determining the call off by detecting the blocking also corresponds to an application of the present invention.

As described above, the portable player 200 to which the hands-free function is added and the driving method thereof according to the present invention are different from the prior art, and the user drives the portable player 200 without changing a separate hands-free or headphones. When the portable terminal 100 is called while listening to the mobile terminal 100, the user can be conveniently added to the portable player 200 as a hands-free function so that the user can make a call by simple switching.

The detailed description of the invention has been described with reference to specific embodiments of the invention as examples, but the invention is not limited thereto, and one having ordinary skill in the art to which the invention pertains without departing from the concept of the invention. Modification or modification of the invention in various forms by the ruler is of course included in the concept of the present invention.

As described above, the portable player to which the hands-free function is added and the driving method thereof according to the present invention can add a hands-free function to the portable player so that a call can be made through the portable player without changing to a separate listening means. By outputting music to create a different atmosphere to the user, the user's convenience is improved, and the contents of the call are stored in the portable player instead of the data storage unit of the limited portable terminal.
